The one that's the most neglected is natural lighting. Light pipes, solar collectors, and microprism window treatments are all available.

The second thing is white paint. You need less outdoor lighting if the built environment absorbs less light.

This does not solve the problem of filling city centers with huge company logos, adverts, signs for casinos or night clubs.
